Changing careers at 6 years into a job, is it realistic? (Salt Lake City)

I want to move from school bus driver to something with more stability. Any experience at all would help. I have good customer skills and I am comfortable with spreadsheets.

I began with informational chats, then a short online course, then a related entry-level role. It took about 10 months.

Try a small project in the new field before committing. It told me a lot about whether I would enjoy it.
